Answer:
(x−4)²+(y)²=1
Step-by-step explanation:
If you translate this into English, you get something like this:
The y value lies between -1 and 1, if the x value is between 3 and 5, This could very well be a circle with the center point M and a radius of 1.
The x-coordinate of the middle lies between 5 and 3, which is 4
The y-coordinate of the middle lies between -1 and 1, which is 0.
So the middle is (4 , 0) and radius is 1
The circle equation (xa) 2 + (yb) 2 = r 2
The circle with center M( a b ) and radius r has as a comparison:
(x - a)² + (y - b)² = r²
with a = 4 and b = 0 and r = 1
(x − 4)² + (y - 0)² = 1²
(x−4)²+(y)²=1
The height of the tree is the sum of the part below the line parallel to the horizontal and the part above the line parallel to the horizontal.
Height of the part below the line parallel to the horizontal = 18 sin16° = 4.96 meters
Horizontal distance of the tip of the of the shadow from the tree = 18 cos16° = 17.30 meters
Height of the part above the line parallel to the horizontal = 17.3 tan68° = 42.83 meters
Height of the tree = 4.96 + 42.83 = 47.79 meters
